Fire resistant composite material and fabrics made therefrom

A composite material comprising:

• (a) a planar substrate selected from the group consisting of cotton, rayon, lyocell and blends thereof;
• and
• (b) a film coating coated on the planar substrate, wherein the coating consists essentially of about 10% to about 20% by weight water, about 25% to about 40% by weight ammonium polyphosphate, about 15% to about 25% by weight acrylic binder material, about 0.5% to about 5.0% by weight cross-linking material, about 5% to about 10% by weight aluminum trihydrate, about 5% to about 15% by weight prefabricated microcells, about 0.1% to about 1.0% by weight thickener material, about 1.0% to about 8.0% by weight surfactant and surfactant-generated microcells, and about 0.1% to about 2.0% by weight catalyst,
• wherein said binder material bonds the ammonium polyphosphate, cross-linking material, aluminum trihydrate, prefabricated microcells, thickener material, surfactant, surfactant-generated microcells and catalyst together and to the substrate such that the substrate is coated with said coating, and
• wherein said composite material is drapable.
